Abstract

The asymptotically distribution-free (ADF) test statistic for covariance structure analysis (CSA) has been reported to perform very poorly in simulation studies, i.e. it leads to inaccurate decisions regarding the adequacy of models of psychological processes. It is shown in the present study that the poor performance of the ADF test statistic is due to inadequate estimation of the weight matrix (W = gamma -1), which is a critical quantity in the ADF theory. Bootstrap procedures based on Hall's bias reduction perspective are proposed to correct the ADF test statistic. It is shown that the bootstrap correction of additive bias on the ADF test statistic yields the desired tail behaviour as the sample size reaches 500 for a 15-variable-3-factor confirmatory factor-analytic model, even if the distribution of the observed variables is not multivariate normal and the latent factors are dependent. These results help to revive the ADF theory in CSA.

Genetic sensitivity to 6-n-propylthiouracil (PROP) and hedonic responses to bitter and sweet tastes.

Genetically mediated sensitivity to the bitter taste of 6-n-propylthiouracil (PROP) has been associated with greater acuity for bitter and for some sweet tastes. Thus far, few studies have explored the relationship between PROP taste sensitivity and hedonic responses to bitter and sweet. In this study, 87 normal-weight young women were divided into PROP non-tasters (n = 18), regular tasters (n = 49), and supertasters (n = 20), based on their PROP detection thresholds and the scaling of five suprathreshold solutions of PROP and NaCl. Non-tasters had thresholds > 1.8 x 10(-4) mol/l PROP. Supertasters had thresholds < 3.2 x 10(-5) mol/l PROP and PROP/NaCl ratios > 1.70. As expected, dislike of the bitter taste of PROP was determined by its perceived intensity, which was greater among supertasters than among regular tasters or non-tasters. Significant correlations were observed between PROP taste thresholds and the sum of intensity ratings (r = -0.61) and between summed intensity and summed hedonic ratings (r = -0.80). PROP taste sensitivity was weakly linked to enhanced perception of sweet taste, but did not predict hedonic responses to sucrose or to saccharin solutions. Given that the dislike of PROP solutions is determined by their perceived intensity, hedonic responses to PROP solutions may provide a rapid way of screening for PROP taster status.

Prospects for the assessment of normal and abnormal interpersonal behavior.

The Interpersonal Adjective Scales (IAS) and the Inventory of Interpersonal Problems (IIP) are current representatives of a long-standing tradition and their use as assessment instruments is expected to become increasingly widespread in the near future and beyond. The IAS is a direct descendent of the interpersonal circumplex tradition and is characterized by an extraordinarily close relation between theory and method in the assessment of both normal and disordered personalities. The IIP stems from a more recent conceptual distinction between psychiatric symptoms and problems of living that has been linked directly to the interpersonal circumplex. This review is meant to alert clinicians to promising supplements to traditional intrapsychic and symptomatic psychodiagnostic batteries.

An improved questionnaire for assessing quality of life after acute myocardial infarction.

This paper reports our experience with the use of an improved self-administered questionnaire for assessing quality of life (QOL) after acute myocardial infarction. The modified questionnaire significantly increased the proportion of patients able to answer all questions from 84%-92%. The additional questions in the improved questionnaire increased the total variance explained by the Emotional, Physical and Social QOL factors from 65.8%-66.5%. Internal consistency and construct validity were assessed and found to be high. Overall, we have found that this improved questionnaire is easy to administer and that it possesses desirable properties of validity and reliability.
